To all whom it limsy con/(Bern:

Be it known that 1, PETER EYERMANN, a citizen ofthe United States, residing at Beloit, in the;coui1ty of Rock and State of Wisconsin, have invented a new and useful Improvement in Producer-Gas Plants, of which the following is a specification.

My invention relates to improvement in apparatus for-the purpose of cleaning, cooling, and storing gas. producergas plants manufacturing lean power or heating gas having a heating value of not more than 200 BTU may thus be.

treated for the use especially in internalcombustion engines, but equally well adapte ed 'for other gas-consuming appliances, like furnaces, &c. I attai'nthese objectsby the mechanisms illustrated in the accompanying drawing, in which- A Figure 1 is a vertical longltudinal. view through a producer-gas plant in-accordance with my invention, parts"being shown in elee vation and applied to a gas-engine of .the vertical type.

Similar throughout the drawing. I As is generally known, the gases escaping from producers are first passed through scrubbers. They are generally in use, and no producer-gas plant is known to me to-day which would have no scrubberl These scrubbers consist generally of stationary or built to-day. As Well known, the suction producer-gas plant of to-day requires between the producer and the consumer only a wet scrubber and sometimes a dry purifier andbesides to a certain extent a gas-reservoir. The pressure producer gas plant. requires, however, the wet scrubber, the dry purifier, sometimes a fan, similar to my Patent No. 785,724, and a holder, the latter similar to those as known in illuminating-gas plants.

These scrubbers and holders or reservoirs are very heavy and require mostly much floor space and room. According to my invention these means are entirely avoided, which means reducing the parts between the producer and the consumer, thus cheapening the roducergas plant and reducing the Weight and room considerably. I obtain this improvement by connecting the fan The gas from any ing 10 by-an convenient device.

letters refer to' similar parts blades may according to my invention, directlyin the fan 7 3 bypipe 4. This fan is directly driven by belt 5 andpulley 6 from a pulley or the fiywheel 7 of the gas-engine 8. If'the gas-engine 8, driven from the gas of said fan, produces electricity, then it may be,v according to conditions, advisable to drive the fan by an electric motor. also by power from anyother source or by a smaller gas-engine, using the same gas. This fan is provided with a water-supply pipe 9. Thewater is used inside of the fan for cooling and cleaning and may be injected in the eas- The fane of an ,waste water is stored mthe lower part of the fan-casing IL or in a'con'nected vessel and overflows through pipe 12 to a water-trap, as generally known, and therefore not shown in drawing. It is now evident that four dis-- tinct actions take place inside of said fan: .(A) suddenly and intensely cooling of the gas by the injected cold liquid; (B) thoroughly cleaning of the gas; ((1) the volume of the escaping hot gas of the producer is considerably reduced'by passing throu 'h that fan; (D) the low-pressure gas from t e producer is converted in gas of higher pressure for the consumer by" the action of said fan. This fan is provided with a by-pass pipe 14, which branches oil from the main gas-pipe 13. The surplus of gas from' the fan flows back in the supply or suction pipe 2 from the producer to thefan. This circulating-pipe 13 may be controlled by a valve 15 in any desired place. There is to note now, as another main point in my invention, that this by-pass servesto 'a certain degree here as a gas-holder by equalizing the pressure. gas takes place in this fan device. That portion of the gas which has been passing through the .circulating-pipel i is cleaned and stored over and over again by passing through the fan. The points of my invention are therefore the use of said fan instead of a scrubber and in addition a by-pass in desired shape The Said fan canbe driven A certain cleaning oi the p der certain conditions it might be desired to or supplied inany other way.

use parts of the wasted cooli11g water for the above-described cleaning purpose or any, other liquid which maybe used for cooling the gas-engine. "A pipe connection 18 is provided for this purpose, and the required liquid for the fan flows then in the direction of The air for the-internal-cornis sucked. by anair-pipeZQ, The exhaust of the engine is at 21. and the main coolingwatez-supply pipe at 22for the engine and at 23 for the. fan. Another auxiliary device is shown'in this gas power plant in 'Fig.- 1 by p 25 between the 26 of the producer and the gas-es- 14 from the fan. This seethe arrow 19. bustion enginechimney ing of gas directly to the atmosphere. T he quantity of this gas can be regulated by a It is also possible to connect the gas and waste-gas pipes 21 25 26 in one pipe. (Not shown indrawing, as this arrangement depends from local conditions.)

Although I have shown my improved producer-gas plants in some detail, I would have it understood that this invention is subject to many changes and nmdifications which can ed by those fainillar-wlth the art;
